rate for Z=120 is predicted for the most mass asymmetric projectile/target combination 54Cr + 248Cm. However, at SHIP no radioactive targets could be used up to now. Therefore, we took the reaction 64Ni + [...] identify Z=114 as shell closure, we investigated as further candidate Z=120. Three different projectile-target combinations lead to the same compound nucleus 302120: 64Ni + 238U, 58Fe + 244Pu and 54Cr + 248Cm [...] chain of element 120 was found. With the total number of 2.6×1019 projectiles which impinged the target, it converts to an upper cross-section limit of 90 fb. From this result we can deduce, that the stability
